To all whom it may concern: Be it known that we, J oHN SPERRY and J OHN,H. EBY, citizensof the United States, residing, respectively, at Kawcity, in the county of Kay and; State of- Oklahoma, and at Carrington,in the county of Wells and State of North Dakota, have invented certainnew and useful Improvements-in Power Apparatus, of which the followingis a specification. 1

Our invention relates to improvements in power apparatus.

The object of our invention is to a power apparatus which may be adaptedto a variety of uses Our invention is particularly well adapted for farmuse for such purposes as running corn shellers, grindingamachines, orfor drawing the rope of hoisting devices, such as hay hoisting machines.

The novel features of our invention are hereinafter particularlydescribed andclaimed,

In the accompanying drawings which provide readily illustrate thepreferred form of our invention.Figure 1 is a plan view, a portion ofthe power lever being broken away. Fig.2

1s a vertical sectional view, taken on the Fig. 3' is a; verdotted linea,b of Fig. 1;

the dotted line tical sectional view taken on c0Z of Fig. 4. Fig. 4 isahorizontal section i taken on the dottedline e f of Fig. 3. Fig. 5 is aplan view of a portion tive rack and some of the from the gear wheelwhich operates it.

Similar characters of reference denote similar parts.

The framework of the machine comprises two vertical side members 1, uponthe upper edges of which is secured a horizontal plat form Rotativelymounted in the side walls 1 is a horizontal rotary driving shaft 3, oneend of which has secured, to it any suitable type of coupling device 4,;bywhich the shaft may be connected, to the driving shaft of-a corn'sheller, grinding machine, or any other machine, not shown.,R-otatively mounted on the driving shaft 3 is a drum 5, provided'at itsends with the heads 6 and 7. Rigidly secured upon the shaft withinthedrum 5,, is a clutch member 8, provided at one end with a-circularrowofratch'etteeth :9, adapted to engage with corresponding teeth 10,disposed concentrically :on' the inner end of the head The outer end-ofof the reciprocaparts connected therewith, the rack being showndisengaged adjacent edge of the head 7 is also provided with a circularrow of ratchet teet 10, adapted to engage a corresponding row of teeth9, provided on the adjacent end of a spur gear wheel 11, which isrigidly secured upon the shaft 3 and meshes with a spur gear wheel 12rota? tively mounted upon a stud 13 secured horizontally to the adjacentside member 1 of the frame. The gear 12 meshes with a horizontal crowngear wheel 14 which is rotatively mounted upon a vertical, rotarycontrolling shaft 15, which is rotatively mounted in the platform 2 andin a horizontal bar 16, the'ends of which are secured to the two sidemembers 1.

A right angled power lever 17, is rigidly secured to the upper end ofthe shaft 15 and has its longer arm extending horizontally throughaninverted U-shaped yoke 18, in which the lever 17 is horizontallyoscillated relative to the rotary member or crown gear wheel 14. Theyoke 18 serves as an abutment against which the power lever 17 has abearing when said power lever is revolved in the direction indicated bythe arrow in Fig.1. To the outer end of the shorter arm 19 of the powerlever, is secured a bolt 20 provided at one end with an eye 21 to whichis secured one end of a coil spring 22, the other end of which issecured to a bracket 23 which in turn is secured to the upper side ofthe rotary member or crown gear wheel 14. The function of thespring 22is to normally retract the power lever 17 in a direction 1 opposite thatindicated by the arrow in Fig.

To the outer end of the power lever 17 may be secured a doubletree 24,as shown in Fig. l.

A plurality of supporting rollers 25 are rotatively mounted in recessesprovided vertically in the rotary member 14. These rollers rest upon acircular track 27, secured to the upper side of the platform 2, as shownin Fig. 2. Brackets 28 are secured to the upper side of the platform 2,around the periphery of the rotary member 14 and have their inner endsprojecting over the upper side of said rotarymember. These bracketsserve to prevent the upward tilting of said rotary member. v

Rigidly secured upon the shaft 15, below the platform- 2 is a horizontalspur gear wheel 29, adapted to engage teeth 30 on the a horizontal rack31, which 1s reciprocatively mounted in downwardly extendingbearings 32,whichare secured to the underside of the platform Pivoted to the upperside of the rack 31, is a pawl 33, which is normally forced against aprojection 34 on the upper side of the rack, by means of a spring 35,which is secured at one end to a vertical pin 36, secured to the upperside of the rack 31. The disposition of the teeth 30 on the rack 31 issuch that when the gear wheel 29 is rotated in the direction indicatedby the arrows in Figs. 1 and 4, the rack 31 will be forced out ofengagement with the gear wheel 29, as shown in Fig. 5. When in thisposition, however, the spring 35 wi.l retain the pawl 33 in engagementwith the gear wheel 29, so that if that gear wheel is retracted in theopposite direction the pawl will be forced against the projection 34 andspur gear wheel 29.

the rack will thereby be retracted to the position shown in Fig. 4.

The object of reciprocating the rack 31 is to cause the drum 5 toalternately be locked with and unlocked from the driving shaft 3. Toaccompish this result the following described mechanism is preferablyemployed:-A nearly vertical bar 37 has its upper end pivoted to the rackbar 31 and its lower end pivoted to a bracket 33. secured to the innerside of the adjacent side member 1. A horizontal link 39 has one endpivoted to the bar 37 and its other end pivoted to a vertical lever 40,the upper end of which is pivoted to a horizontal pin 41 which extendstransversely across a recess 42, provided in the underside of theplatform 2. The head 6 of the drum 5 is provided on its outer (ill witha cy.indrical, axial hub 43, to which is secured a collar 44. Encirclingthe hub 43 and s.idable lengthwise thereon, is a ring 45, best shown inFig. 3. This ring is normally held against the inner end of the collar44 by a coil spring 46, which encircles the hub 43 and at its inner endbears against the head 6. The collar 44 and the ring 45 form betweenthem an annular groove 47, in which is located the lower end of thelever 40. The outer end of the rack bar 31 extends through a slot 48provided in the adjacent side member 1 and at its outer end ispreferab'y provided with a hand held 49, by means of which the rack bar31 may, when desired, be manually held in a position disengaged from thegear wheel 29, as shown in Fi 5.

50 denotes a rope. one end of which is secured to the periphery of thedrum 5. This rope is adapted to be wound upon the drum 5 when the powerlever 17 is revolved in the direction indicated by the arrow in Fig. 1.In devices such as hay hoisting devices, it is desirable to wind therope 50 upon the drum so as to hoist the hay in the manner common withsuch devices. It is also desirable, when the load has been raised to theproper height. to quickly release the drum 5 from the shaft 3 so thatthe drum may be freely revolved and the rope with- \volve rotation in alike l desired to release the drum 5 from the shaft 13l drawn therefrom.To effect this result the following described method of procedure isemployed: l he horse or horses which are attached to the doubletree 24are driven so as to revolve the power lever 17 in the direction denotedby the arrow in Fig. 1. 'l he power lever in its forward movement willstrike the abutment or yoke 18 and its continued movement will causerotation of the crown gear wheel or rotary member 14 in a like directionRotation of the rotary member 14 will be transmitted to the drivingshaft 3 by the gear wheels 12 and 11. As soon as the power lever 17 isstarted to redirection will be imparted to the controlling shaft 15 andthe Such rotation of the gear wheel 29 will force the rack bar 31 out ofengagement with the spur gear wheel and into the position shown in Fig.5. Movement of the rack bar 31 in this direction will cause the lowerend of the lever 40 to be swung, through the intermediacy of the bar 37and link 39, toward the head (3 of the drum 5. 'l he lever 40 in somoving will bear against the ring 45 which in turn will press againstthe spring 46 which is of sullicient rigidity to cause it to move thedrum 5 lengthwise 011 the driving shaft 3, into a position in which theteeth 10 on the heads 6 and 7 will lcckingly engage the teeth 9 of theclutch member 3 and spur gear wheel 11 respectively. The drum 5 willthereby be in locked engagement and will rotate with the driving shaft3. thus causing the rope 50 to be wound upon the drum.

'1 he function of the spring 46 is to provide a resilient bearing forthe lever 40 so that in case the drum should be in position such thatthe teeth 10 would strike the outer ends of the teeth 9 the spring 46would yield and thereby prevent any breakage of the parts.

When it is desired to free the drum 5 from the driving shaft 3, thehorses attached to the doubletree 24 are stopped so as to relieve thepulling strain upon the power lever 17. 'lhe power lever 17 being freeto oscillate will be retracted by the spring 22 to the. position shownin Fig. 1. Such retraction of the power lever will be communicated tothe shaft 15 and gear wheel 29. lietraction of the gear wheel 29 willcause it to engage the pawl 33, as hereinbefore described, therebyretracting the rack bar 31 to the position shown in Fig. 4. Suchretraction of the draw bar 31 will, through the intermediaey of the bar37 and link 39, cause the lever 40 to swing outwardly against the collar44, thereby sliding the drum 5 lengthwise on the shaft 3 to the positionshown in F 3, in which position it will be disengaged from the clutchmember 8 and gear wheel 9, and will be free to rotate on the shaft 3. Incase that the horses should be stopped and it is not 3, pressuresufficient to overcome the strength of the spring 22 is manually appliedto the outer end of the rack barv3l in a' direction such as'will preventthe outward forcing of said bar.

Our invention may be modified in many ways within the scope of theappended claims without departing from its spirit.
